Galvanized pipe corrosion causing hidden leaks
Why it happens here
Galvanized steel pipe rusts from the inside out, and after 60 or 70 years the wall thins enough to split under normal pressure. South Berwyn's pre-1950 homes are full of this pipe, and the leaks often start behind walls where no one sees them.
Our approach
We inspect the full run with an inspection camera and replace any section with heavy corrosion using copper or PEX. Patching a galvanized line that is already failing is a waste of money, and we tell you that upfront.
